Y MILK DISPENSER.

Application led July 12, 1923.- Serial No. 651,002.

To @ZZ whom t may concern:

Be it lniown that I, ALFRED L. MORON, a citizen of the United States of America, and a resident of East Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Milk Dispensers, of which the following is a specification.

This invention relates to devices for dispensing liquids in restaurants, lunch rooms, and like places, the principal object of the invention being to provide a device of this character in which a thorough lmixture of the liquid is assured each time a portion of the liquid is removed from the container, thereby insuring that all customers will be treated alike. i

The invention is primarily adapted for dispensing milk and consists of a container provided with a coolingcompartment enclosing the milk tank, in which is disposed a perforated receptacle containing acupshaped milk lifter.

The invention further consists ,in providing' the cup-shaped milk lifter with a valve. in the bottom thereofwhich will open during the lowering of the lifter and which will close during its upwardv movement.

The invention further consists in provid ing the lifter with a valve in its vertical wall which is designed to be closed during the lowering of said lifter and during the raising of said lifter until it reaches its highest position, at which point this side valve will open and permit the contents of the lifter to flow therefrom into a downward passage, at the bottom of which is the delivery faucet. 1

. The invention further consists in means on the outside of the tank for raising and lowering the cup-shaped milk lifter.

The invention further consists in certain novel features of construction and arrange ment of parts which will be understood readily by reference to the description of the drawings and to the claims to be hereinafter given.

For the purpose of illustrating the invention, one preferred form thereof is shown in the drawings, this form having been found vto give satisfactory and reliable results, although it is to be understood that the various instrumentalities ofV which the invention consists can be variously arranged and organized, and that the invention is not limited to the precise arrangementand organization as herein shown anddescribed, except as required by the scope of the appended claims. Of the drawings: Y.

Figure 1 represents alvertical section of a device embodying the principles ofthe present invention.

Figure 2 represents a horizontal section of same on line 2, 2 on Fig. 1.`

Figure 3 represents a partial side velevation of saine, a portion thereof being in section, and

Figure 4 represents an elevation of the locking device.

Similar characters indicate like parts throughout the several figures of the drawings.

In the drawings, 10 is a liquid-container provided with a cover 11.

The'walls of the container are provided with 'chambers 12 filled with ground `cork or some similar material.

The container rests upon legs 13, 13 and Athe inner face of its bottom has upwardly extending lugs 14 upon which is positioned a tank 15.

The tank 15 is provided with a passage 16 open at the top and closed at the bottom, said passage 16 being formed byA a U-shaped plate 17 soldered or otherwise secured to the inner face of thewall of said tank.

The tank 15 has a tubular hub 181eXtending outwardly therefrom, the bore of which communicates with the lower end of said passage 16. l

The outer end of said hub 18 is coneshaped and fits a conical depression `19 in the inner face of the wall of said container, said depression `surrounding anA opening 20 through said wall.`

At the outer end of said opening is another conical depression 21, `to which is tted a cone-shaped Yportion of the faucet 22.

The faucet is provided with a tubular shank which extends through the opening 2O and has its inner end threaded to the core of the hub 18. Y

wWhen the faucet 22 has been properly* positioned, the end of the hub 18 and the cone-shaped portion .of .the faucet 22 will be drawn tightly into the depressions 19 and 21' and make a perfectlyV tight joint from which can leak none of the iced water placed in the container 10 around the tank 15.,V

Il f) A pet cock 23 is provided by which water may hedrawnfromthe container l when desiredl f" 1 This pet cock may be of any well known construction.

The wall of the container l0 extends above the wall of the tank 1S, and resting upon the latter wall is a two-part cover 2li, 25, having an annular inclined portion 26 extending downwardly from the wall of the container.

-rlhis two-:part cover 24, closes the upper end oi"y tliefice chamber 2'@ v` l @ne part-2st ot vthe cover has an opening 28 therethrough provided with a closure 29 which may be removed when it is desired to pour a. fresh supply oil niilk'or other liquid into they 'tank l5.

Positioned in the tank l is a perforated cylinder 30 provided at the bottom with positioning legs 3l` to reta-in said cylinder 30 centrally disposed within the tank 'rit the top ot the cylinder is alateral arm 32, the outer end of which hears against the wall of the tank l5.

liVithini the cylinder 30 is disposed the lifter 33,1Whic'h is cup-shaped as shown in Figi 1,1`a`nd provided `with a peripheral per- Aliorated flange 34 extending to the wall of saidrylindeiSO.

The bottom of the lifter 33 has an opening 3s therein, adapted to. be closed-by the ball Pio'when the lifter is raised in the cylinder 80.

A cage 3G extendsv over the ball 35 and limits'its"movement and` prevents the nisplacement thereof, when the litter 33 is beingA moved ldownwardly within the cylinder 30.

Atene side of the cylinder 30, the wall thereoix projects outwardly beyond the periphery or said cylinder as at this proj ec-y tion extendingfrom the bottomr ot the cylinder to the top thereof', and near the top it is provided with an outlet opening 38 into the upper end of the passage 39, the lower end of' which has an outlet through the faucet 22.

*The cup-shaped litter 33 has a hub e() ei;- tending' laterally therefrom, with an openingtherethrough, the outer end et the opening having a seatfor a ball 11:2 a portion of which bears against the wall ot the projecting portion 3?.

Y is theliiter is raised, the ball 42 will be retainedagainst its seat by` said wall and v/'illclose thev opening el'.

lVhen the ball l-.2'reaches the point i3 it willy infove'doiwn the inclined surface 44 and permit the liquid in said lifter to flow thereiroinfthrough the opening il into the passage 39 Jfrom which it may he drawn ofi, through the faucet 22.

' 'The opening 3d is of such size as to permit tlieball tov extendpartially through the same that when the lifter 33 is in its lowest position, as indicated in Fig. l., the ball will be raised slightly to permit liquid to flow through said opening.

As soon as the litter isvraised, however, the ball will be forced to its seat and close the opening so that no liquid can pass therethrough.

'lfhe lifter can be made of such size as to measure oli" a full ot milk or other liquid each time it is raised in the cylina der 36.

The cup-shaped member 33 has secured. thereto a diametrically disposed rod to which the lower end of the lifting rod lo is connected.

rlhe upper end of the roc 4t' extends through the cover ll and has ahead l? threaded thereto, against the under il? ce ol which bears the upper end oi: a rod 48, the ower end of which is mounted in a block i9 slidably positioned in the vertical guide-way 5G on the outer tace oit the wall of the container i0.

ln the lowerY end oi the guide-way is a spring :'il, against which the block Li9 cornes into contact when said block reaches its lowest position thereby obifiating any shocl.

The block 49 has a headed stud o2 projecting therefrom on which r rolubly mounted the knob by 'which the `block i9 may belowered when it is desired to dispense the liquid within the tank rilhe rod 48 has a shouldered projection 48 between which and the top plate 54 or' the guide-way 50 is a helical spring which normally retains the block i9 in its highest position with the lifter 33 at the top et the perforated cylinder 30.

Secured to the upper end 'et the guide-way 50 is a plate 56 having a pin 57 extending therefrom' and with which the hook is adapted to engage to retain the litter 23 in its highest position.

The hook is adapted to nieve about the axis oit the pin 5l, between the pins 59 which limit the movement oi said'hook in either direction.

The cylinder 30 is provided with a plurality ot perfor-ations o() in the side and bot toni thereof, through which the liquid in thetank lo is athii'itec` to freely flow.

llJhe-n it is desired to dispense'liquid trou" the tank lo the operator releases thehoolr: from the pin 5'? by turning the knob contra1 clockwise, and he then, still grasping vo toe knob, forces the block downwardigY hottoin oi the guide-way of).

This downward movement ot the bloei` and rod 41S connected thereto will impart a downwarur movement to the rod '46 and the liquid litter secured to the lower end thereo'?.

its the lifter 33 inoves downwardly, the ball 42 will be orcfedl to its seat by Contact with the wall 37, thereby closing the opening 4l, and at the same tiine the ball will llO be forced upwardly in its cage 36, uncovering the opening 34 in the bottom of the lifter 33 and permitting the liquid in the tank l5 to enter and fill the lifter 33.

The downward movement of the lifter will displace' the liquid beneath it and cause it to circulate in the tank l5 and through the perforations 60, substantially as shown and described in another application of mine filed December 8, 1922, Serial No. 605,627.

Every downward movement of the lifter 33 will cause a thorough mixture of the liquid in the tanl; so that the same quality of liquid will be dispensed to each customer.

When the block 49 is raised, the spring 5,5 assists in carrying the load of liquid contained within the lifter 33.

As the lifter 33 is raised, the ball 35'will close the outlet 34 and the lifter will be lled with liquid.

When the lifter passes the point 43, the ball 42 will be free to move down the inclined surface 44 and Auncover the opening 41, permitting the liquid in the lifter 33 to flow into the passage 39 from which it may be withdrawn through the faucet 22.

All of the parts may be taken apart readily to permit them to be thoroughly cleansed.

This makes a very convenient apparatus for dispensing liquid and particularly milk in lunch rooms and restaurants.

it is believed that its operation and many advantages will be understood readily without further description.
